This tutorial describes How to fix Bringing up interface eth0: Error: No suitable device found: no device found for connection 'System eth0'.

My Scenario:-

I Successfully converted my Linux Centos 6.5 physical box into virtual environment using VMware VCenter Converter standalone. After the P2V conversion all the services are running perfectly except network adapter eth0 is not started. I realized there is some problem with network adapter. Identified eth0 retain physical server MAC address that is the cause of the error[Error: No suitable device found: no device found for connection 'System eth0'.].

Step #4: Restart the Linux box and restart the network service to apply changes.

[root@server1~]# init 6
[root@server1~]# service network restart

Still if your facing the issue. Change the NM_CONTROLLED yes to no in eth0. Restart the Linux box and restart the network service. once everything is back to normal change the NM_CONTROLLED no to yes and Restart the Linux box and restart the network service.

I hope this information is useful for you. Please forgive any typos or incomplete sentences.

I don't understand - you change your eth0 config file so that it has a hardware address of "00:0C:29:D0:C9:FE", but where did you get this value? Your example above it seems to show that the eth2 hardware address is something entirely different?
